Dachau is 20 km (12 mi) northwest of Munich. It is 482 meters above sea level by the river Amper, with a boundary demarcated by lateral moraines formed during the last ice age and the Amper glacial valley. It is also close to a large marshy area called Dachauer Moos. Highest elevation of the district is the so-called "Schlossberg", the lowest point is near the neighborhood of Prittlbach, at the border to the next community of Hebertshausen. The bordering communities are Bergkirchen to the west, Schwabhausen to the northwest, Röhrmoos to the north, Hebertshausen to the northeast, and Karlsfeld to the south. To the east the greater district Dachau borders on the greater district of Munich with the community of Oberschleißheim.
State of Health. The incidence of disease is very high here in proportion to the number of detainees. When you interviewed me on Dec. 1, 1944, at Oranienburg, you told me that Bergen-Belsen was to serve as a sick camp for all concentration camps in north Germany. The number of sick has greatly increased, particularly on account of the transports of detainees that have arrived from the East in recent times -- these transports have sometimes spent eight or fourteen days in open trucks ...
The shaven-headed prisoners in blue-striped clothes were numbers, not persons, stripped of their humanity and individual personalities. They were referred to as "pigs" and "filth" and other obscenity-laced names. Jews especially were referred to as "filth-Jews" or "trash-Jews." Upon first entering Dachau and being registered, a Jew would be asked: "The name of the whore that shitted you out?" – to which they had to give their mother's name or be beaten.
Jewish prisoners were concentrated at Bergen-Belsen, hitherto not known as one of the worst camps; but in the chaotic final months of the war conditions were allowed to deteriorate catastrophically. When British troops came across the camp on 15 April 1945, they encountered 10,000 unburied corpses, a raging typhus epidemic and 60,000 sick and dying prisoners crammed into overcrowded barracks without food or water.
Dachau was never a camp that was specifically intended for murdering the Jews; the Nazi plan was to consolidate all the Jews into ghettos, from which they were later sent to the death camps. German Jews were sent to the Lodz ghetto in what is now Poland where they worked in factories until 1944; those who could no longer work were sent to the Chelmno death camp. In 1942, the Jews who were still living in Germany were sent to the Theresienstadt ghetto in what is now the Czech Republic and from there to the gas chambers in Auschwitz-Birkenau.
The camp of Bergen-Belsen, located near the towns of Bergen and Belsen in Saxony, northern Germany, got its start in 1940 as a P.O.W. camp for French and Belgian prisoners. In 1941, the camp was renamed Stalag 311 and housed some 20,000 Russian prisoners. Conditions were terrible, resulting by 1942 in the deaths of 16,000 to 18,000 prisoners from disease, starvation and exposure.
Killing on a mass scale using gas chambers or gas vans was the main difference between the extermination and concentration camps.[269] From the end of 1941, the Germans built six extermination camps in occupied Poland: Auschwitz II-Birkenau, Majdanek, Chełmno, and the three Operation Reinhard camps at Belzec, Sobibor, and Treblinka II.[44][270] Maly Trostenets, a concentration camp in the Reichskommissariat Ostland, became a killing centre in 1942.[44] Gerlach writes that over three million Jews were murdered in 1942, the year that "marked the peak" of the mass murder of Jews.[271] At least 1.4 million of these were in the General Government area of Poland.[272]
Throughout German-occupied territory the situation of the Jews was desperate. They had meagre resources and few allies and faced impossible choices. A few people came to their rescue, often at the risk of their own lives. Swedish diplomat Raoul Wallenberg arrived in Budapest on July 9, 1944, in an effort to save Hungary’s sole remaining Jewish community. Over the next six months, he worked with other neutral diplomats, the Vatican, and Jews themselves to prevent the deportation of these last Jews. Elsewhere, Le Chambon-sur-Lignon, a French Huguenot village, became a haven for 5,000 Jews. In German-occupied Poland, where it was illegal to aid Jews and where such action was punishable by death, the Zegota (Council for Aid to Jews) rescued a similar number of Jewish men, women, and children. Financed by the London-based Polish government in exile and involving a wide range of clandestine political organizations, Zegota provided hiding places and financial support and forged identity documents.
Although many people responded with obstructionism and doubt,  several rescue operations were run throughout Axis-controlled Europe. Some were the work of prominent individuals like Raoul Wallenberg and Carl Lutz who worked largely alone while other operations were far more complex. A network of Catholic bishops and clergymen organized local protests and shelter campaigns throughout much of Europe that are today estimated to have saved 860,000 lives. Danish fishermen clandestinely ferried more than 7,000 Jews into neutral Sweden while the French town of Chambon-sur-Lignon sheltered between 3,000 and 5,000 refugees.

The Nazis used the phrase Lebensunwertes Leben (life unworthy of life) in reference to the disabled and mentally ill.[92] On 14 July 1933, the Law for the Prevention of Hereditarily Diseased Offspring (Gesetz zur Verhütung erbkranken Nachwuchses), the Sterilization Law, was passed, allowing for compulsory sterilization.[93][94] The New York Times reported on 21 December that year: "400,000 Germans to be sterilized".[95] There were 84,525 applications from doctors in the first year. The courts reached a decision in 64,499 of those cases; 56,244 were in favor of sterilization.[96] Estimates for the number of involuntary sterilizations during the whole of the Third Reich range from 300,000 to 400,000.[97]
In March 1943, the Krakow ghetto was being liquidated, and all the remaining Jews were being moved to the forced-labor camp of Plaszow, outside Krakow.  Schindler prevailed upon SS-Haupsturmführer Amon Goeth, the brutal camp commandant and a personal drinking companion, to allow him to set up a special sub-camp for his own Jewish workers at the factory site in Zablocie. There he was better able to keep the Jews under relatively tolerable conditions, augmenting their below-subsistence diet with food bought on the black market with his own money. The factory compound was declared out of bounds for the SS guards who kept watch over the sub-camp.

Immediately after liberation, West European Jews who survived the Holocaust generally returned to their countries of origin. Holocaust survivors who tried to return to their homes in Eastern Europe faced many more difficulties. The Nazi destruction in the East had been all-encompassing. Many survivors, particularly in Eastern Europe, continued to encounter antisemitism when they returned to their communities. In some places survivors who had returned home met with violent hostility. In Kielce, 42 Jews who had survived the Holocaust were killed by local Poles in a pogrom on July 4, 1946.
In December 1944 SS-Hauptsturmführer Josef Kramer, previously at Auschwitz-Birkenau, became the new camp commandant, replacing SS-Hauptsturmführer Adolf Haas [de], who had been in post since the spring of 1943.[7] In January 1945, the SS took over the POW hospital and increased the size of Bergen-Belsen. As eastern concentration camps were evacuated before the advance of the Red Army, at least 85,000 people were transported in cattle cars or marched to Bergen-Belsen.[14] Before that the number of prisoners at Belsen had been much smaller. In July 1944 there were 7,300; by December 1944 the number had increased to 15,000; and by February 1945 it had risen to 22,000. Numbers then soared to around 60,000 by April 15, 1945.[7] This overcrowding led to a vast increase in deaths from disease: particularly typhus, as well as tuberculosis, typhoid fever, dysentery and malnutrition in a camp originally designed to hold about 10,000 inmates. At this point also, the special status of the exchange prisoners no longer applied. All inmates were subject to starvation and epidemics.[14]
